A fresh batch of Drop Liner backpacks, made from NWEAVE® Cuben Fiber® - this fabric was developed by North® for the leading edges of their high-end kites and wings. Designed for long lasting use in harsh marine environments, it is strong and lightweight. Cuben Fiber® is made from essentially the same fiber that Dyneema® is, an ultra-high molecular weight polyethylene.
I got a short roll of this great material as end rolls and dead stock from their kite and wing manufacturing operation.
This batch of 3 is made with seam sealed orange liners from Gore-Tex® drysuit factory scrap, and Fidlock® magnetic closures for the main strap.
